If you like European girls J4L.club is the site that really stands out. I used to meet awesome girls there and I went on vacation with one of them. Anyway, they have real women and they are better than YourTravelMates. YTM is an outrageously expensive fantasy and scam from start to finish! You are buried in computer generated messages, then you chat for days, months and years but no girl would reveal any contact details. They just string you along!
Don't get your hopes up because YourTravelMates girls flood you with chat requests and messages. This is how they make money. It's just their job. They don't have an intention to meet men and travel anywhere. I learned my fair share of lessons there. Do your wallet a favor and just avoid this scam.
